Prevalence of influenza A, C and D viruses in Korean swine farms
Influenza viruses are enveloped, segmented, single-stranded, negative-sense RNA viruses that belong to the Orthomyxoviridae family. There are four types of influenza viruses, influenza A, B, C, and D viruses (IAV, IBV, ICV, and IDV), and only three types of influenza viruses, IAV, ICV, and IDV, can infect swine with zoonotic potential. However, in Korea, the prevalence of ICV and IDV as compared with IAV has not been much studied yet. To determine the prevalence of IAV, ICV, and IDV among swine farms in Korea, 1,602 nasal swabs and 200 oral fluid samples were collected from 40 pig farms betwee...

First molecular detection and genotyping of Psittacid herpesvirus 1 from pet parrot in Korea
To identify the causes of sudden death in pet parrots in this study, molecular screening was carried out to detect major psittacine viral pathogens including Psittacine beak and feather disease virus (PBFDV), Avian bornavirus (ABV), Psittacid herpesvirus 1 (PsHV-1), Avian polyomavirus, and Avian paramyxovirus serotype 1. The results showed that all six parrots were infected with PBFDV, indicating that PBFDV was likely the main cause of their deaths. Among these PBFDV-positive parrots, three were dually coinfected with PBFDV and ABV and one was triply coinfected with PBFDV, ABV and PsHV-1, indi...

The effects of the antiviral agent T-1105 on various serotypes of foot-and-mouth disease virus
Foot-and-mouth disease (FMD) is a highly contagious viral disease that affects cloven-hoofed animals and is caused by the foot-and-mouth disease virus (FMDV), and results in significant economic losses in the livestock industry. The high genetic variability of FMDV poses a substantial challenge to vaccine efficacy. This study evaluates the antiviral efficacy of T-1105, an RNA-dependent RNA polymerase inhibitor, against FMDV. The cytotoxic concentration 50 (CC50) and inhibitory concentration 50 (IC50) of T-1105 were determined, and the sensitivity index (SI) was calculated. Results demonstrated...

A duplex TaqMan probe-based real-time PCR assay for simultaneous detection of Psittacine beak and feather disease virus and Aves polyomavirus 1 from psittacine birds in Korea
Psittacine beak and feather disease virus (PBFDV) and Aves polyomavirus 1 (APyV) are important viral pathogens in psittacine birds worldwide. Early diagnosis and isolation of infected birds are key to preventing the transmission of these viruses to healthy birds. In this study, a TaqMan probe-based duplex real-time quantitative polymerase chain reaction (dqPCR) assay was developed for the rapid and differential detection PBFDV and APyV. The developed dqPCR assay using two sets of primers and probes specifically amplified the PBFDV V1 gene and APyV T gene in a single reaction. The limit of dete...

Effects of bone morphogenetic protein-2 and activated platelet-rich plasma on canine chondrocytes in monolayer cultures
This study evaluated the effects of bone morphogenetic protein-2 (BMP-2) and platelet-rich plasma (PRP) on canine chondrocytes under inflammatory conditions. Four groups were tested: control, BMP, PRP, and PRP+BMP. Inflammatory conditions were induced using lipopolysaccharide. Realtime polymerase chain reaction (PCR) was performed to measure the expression of COL1A1, COL2A1, interleukin (IL)-1β, and osteocalcin, and a cell proliferation assay was conducted. Cell proliferation assays showed significant increases in both PRP and PRP+BMP groups, with no significant difference between them. I...

Correlation between body condition score and serum biochemical parameters in Hanwoo cattle
This study aimed to investigate the relationship between body condition score (BCS) and serum biochemical parameters in Hanwoo cattle, considering the significant changes in body size that have occurred over the past two decades. A total of 45 clinically healthy Hanwoo cattle were categorized into three BCS groups: group 1 (BCS: 3.0∼3.25), group 2 (BCS: 3.5∼3.75), and group 3 (BCS: 4.0∼4.25). Blood samples were collected and analyzed for the total number of 16 biochemical parameters. Significant differences were observed in blood urea nitrogen (BUN), gamma-glutamyl transferase (GGT...

Comparison of acid-base disorders in cats using traditional, Stewart, and Fencl-Stewart methods
This study investigates acid-base disorders in cats using traditional, Stewart, and Fencl-Stewart methods. Analyzing data from 69 sick and 18 healthy cats between 2018 and 2020, it aims to evaluate the frequency and nature of these imbalances across various diseases. Significant differences in acid-base parameters were observed in cats with different health conditions. Hepatobiliary diseases showed notable changes in pH, chloride, base excess, bicarbonate, and other parameters. Urinary diseases affected pH, base excess, and bicarbonate levels, while gastrointestinal diseases impacted pH, base ...

Safety evaluation of live-attenuated vaccine candidate derived from avian pathogenic Escherichia coli serotype O78 isolate
Chicken colibacillosis caused by infection with avian pathogenic Escherichia coli (APEC) O78 serotype can bring about prevalent economic losses and it could be ongoing concern in poultry industry. It is attempted to create a mutant strain of APEC O78 isolate, in order to attenuate the virulence of APEC O78, with a view to creating a potential candidate of live-attenuated vaccine to be used for broiler chickens. A genetic mutation in the phosphate transporter (pst) gene was constructed in this study to lessen the virulence of the APEC O78 isolate. The resulting pst mutant of APEC O78 was verifi...

Nephrectomy with hydronephrosis following ovariohysterectomy using surgical ligation clips in a dog
A 7-year-old spayed female poodle presented with abdominal distension. Initial tests included a complete blood count, serum biochemistry panel, coagulation test, radiography, and ultrasound. As an additional test, a computed tomography urography was performed. Based on the ultrasound and CT findings, an exploratory laparotomy was performed to remove the ligation clip that appeared to be causing hydronephrosis and hydroureter in the left kidney. A ligation clip obstructing the proximal ureter of the left kidney was discovered. All clips, including the obstructing one, were removed, and a nephre...

New technique for incision site selection in laparoscopic-assisted minilaparotomy for canine fistula
A 4-year-old neutered male Shar-Pei, weighing 20 kg, presented with a subcutaneous chest wall mass in the right thorax. The mass measured 12×7 cm with a soft texture and rounded contour. Fine-needle aspiration (FNA), radiography, and computed tomography (CT) revealed a foreign body, suspected to be a wooden skewer, compressing the area between the ribs and diaphragm and extending its impact to the abdominal cavity, thoracic cavity, and subcutaneous tissues. The patient’s primary symptom, the right thoracic mass, was identified as a granulomatous abscess caused by a gastrosubcutaneo...

Gastric leiomyosarcoma in a Himalayan cat
A 2-year-old intact male Himalayan cat was presented with two months history of anorexia, vomiting and loss of body weight. Abdominal ultrasonography revealed abnormal mass in stomach. Surgical removal of gastric pyloric mass 3×3×1.5 cm in size at greater curvature was performed and then was submitted for diagnosis. Histopathologically, large neoplastic foci were occupied from submucosa to serosa in the stomach, and were consisted of interlacing fascicles of spindle cells with marked cellular pleomorphism including anisokaryosis, anisocytosis, and bi-nucleation. Tumor cells showed ...

The dual surgical intervention of cholecystectomy and adrenalectomy in an 11-year-old female dog
An 11-year-old spayed female dog was diagnosed with gallbladder mucocele (GBM), characterized by excessive mucin production that led to gallbladder distension and posed a risk for severe complications. Given these risks, current treatment guidelines recommend surgical intervention, with cholecystectomy being the preferred therapeutic approach. Furthermore, the dog presented with an adrenal gland mass, demonstrating hypertension and markedly elevated levels of metanephrine and normetanephrine, raising suspicion of pheochromocytoma without evidence of invasion or metastasis. This situation enhan...
